P0C02Drive Motor B Current
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0C02 is the general current code for drive motor B, the second electric machine, such as the second motor of a two-motor hybrid or the rear motor of an electric all-wheel-drive system. It applies to a current fault that is neither classed as low (P0C03) nor high (P0C04). No manufacturer documents this exact code publicly. CARB requires monitoring of electric motor performance. The documented relative is P0C04: GM checks the phase current of motor B against 600 to 725 A, and Stellantis lists P0C04 on the 2026 Wagoneer S and Cherokee with faulty three-phase cable joints. With P0C02 stored the controller usually cuts or limits the power of motor B. Inspect the phase cabling, the winding resistance and the inverter of motor B.
